Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to an electronic apparatus, such as a video camera or a digital camera, that employs a fuel cell device as a power source, and a fuel cell control method for an electronic apparatus.

[0003] 2. Description of the Related Art

[0004] For electronic apparatuses such as video cameras, rechargeable secondary batteries are generally employed as power sources. These secondary batteries are, for example, lithium ion secondary batteries, nickel-metal hydride batteries, nickel-cadmium batteries and lead-acid storage batteries. In many cases, for an electronic apparatus that includes a secondary battery, when the power provided by a battery is reduced during a battery-operated period, a low power display is provided via a display unit, and when the available battery power is equal to or lower than a specific level, the power is disconnected automatically.

[0005] On the other hand, fuel cells have b...
